The working principle of the eddy current retarder The eddy current retarder is a device that uses electromagnetism to convert the kinetic energy of the car into heat energy to dissipate it, thereby realizing deceleration and braking. When DC current is applied to the coil winding of the retarder, a magnetic field is generated in each coil winding, and the magnetic field is further strengthened by the excitation magnetic core. The polarity of the adjacent two coils is set to opposite phase. The drum of the retarder cuts the magnetic lines during rotation and generates eddy currents on the inner surface of the drum. After the eddy currents are generated, the magnetic field exerts a force on the carrier-carrying drum and stops the rotation of the drum, ie a braking force is generated. The eddy currents generated in the drum are dissipated into the air as thermal energy through the fins on the drum. The eddy current retarder continuously converts the kinetic energy of the vehicle into the eddy current in the rotating drum, and converts the eddy current into heat energy, which achieves the purpose of consuming the amount of kinetic energy magnetic field and eddy current generated by the automobile. When the current in the coil is cut off, the retarder no longer generates braking torque because it does not act as an electromagnet.
The eddy current retarder has no time lag in the execution of the work, and the current in the coil can be steplessly adjusted to change the magnitude of the torque. At the beginning of work, there is no impact and noise. The installation method of eddy current retarder, the installation method of eddy current retarder The installation position and form of eddy current retarder on the vehicle is mainly the central deceleration installation method, ie the eddy current retarder is installed in the middle of the axle. To control the braking reduction of the entire axle. The braking torque generated by the eddy current retarder first acts on the transmission shaft and is then distributed to the left and right driving wheels, thereby decelerating the entire vehicle. Even when the braking torques obtained by the drive wheels on the two sides are different, because they only take part of the braking torque and occupy a small part of the entire braking torque, it is still possible to effectively prevent the occurrence of brake runaway. This kind of installation method is divided into three kinds, namely to install in the transmission output shaft end, the transmission shaft or the main reducer input end three places. In order to ensure sufficient connection strength, the transmission housing needs to be matched.
Electric Scooter Protective Gear is the basic protective equipment of Electric Scooter;
Like most out door sports, MKARDA GROUP suggest the electric scooter users should
wear the protective equipment, such as Electric Scooter Helmets, Scooter Gloves and electric Scooter Protective Gear.
Short distance transport tools is a very funny and relax sport, especially for the children;
MKARDA group suggest users protect your body first and entertainment second.
